By Scott Patterson In the U.S., government and environment activists are pressuring its people to convert from using old traditional incandescent lamps to LEDs (Light-Emitting Diodes) and CFLs (Compact Florescent Lamps). The public resist the notion that their freedom of choosing the type of lights they can use being strip away. Radio talk-show and TV-show hosts have rebelled and said that the new policy is unconstitutional. The government has no rights to tell its people what kind of light they can use. This adaption process will take time as what we hav...

Source from : Chi Long Machinery Co., Ltd There are three kind methods of LED lamp heat-sink, incl. conduction, convection and radiation. The existed heat-sink design is focus on the conduction and convection for LED lamp. In the radiation aspect, many companies did not pay attention on it. But the radiation is a very important factor for LED lamp. The existed conduction heat-sink of LED lamp is just in view of the internal conduction only. That is conducting the heat of LED lamp to the radiator fin and to apply the radiator fin to bring the...

An average American town’s biggest expense, when excluded payrolls, typically lands on its reoccurring street lighting bill.
